Simulation assisted capacity improvement of cement grinding circuit

Research highlights Extensive sampling campaign was performed around the cement grinding circuit of a cement plant in Turkey for the modelling and simulation purposes. Ball size adjustment was the major optimization for the capacity improvement for that case study. The capacity of the circuit was increased up to 12.7–20.5% for different Milling operations in various production processes are among the most important factors in determining the quality, stability, and consumption of energy. Optimizing and stabilizing the milling process is a non-linear multivariable control problem.
